Environmental pollution, especially water pollution caused by dyes, heavy metal ions and biological pathogens, is a root cause of various lethal diseases in human-beings and animals. Water purification materials and treatment methods are overpriced. Consequently, there is an imperative outlook observance for cheap materials for the purification of wastewaters. In order to fill up the projected demand for clean water, the present study aimed to make use of cost-effective and environmentally friendly methods to convert bone-waste from animals such as cows into novel composites for the decontamination of water. The bone-waste of slaughtered cows from the Najran region of Saudi Arabia was collected and used for the synthesis of hydroxyapatite based on the thermal method. The synthesized hydroxyapatite (Ca(PO)(OH)) was utilized to prepare a manganese ferrite/hydroxyapatite composite. The nanocomposite was categorized by diverse sophisticated procedures, for instance XRD, FE-SEM, EDX, TEM, UV, PL and FT-IR. This composite possesses outstanding photocatalytic activity against methylene blue dye, which is a common pollutant from industrial wastes. Moreover, the synthesised composite revealed exceptional bacteriostatic commotion towards and bacteria, which are accountable for acute waterborne infections. The outcome of this study demonstrated that the integration of manganese ferrite into hydroxyapatite significantly intensified both antimicrobial and photocatalytic actions when compared to the virgin hydroxyapatite.
环境污染，尤其是由染料、重金属离子和生物病原体引起的水污染，是人类和动物各种致命疾病的根本原因。水净化材料和处理方法价格过高。因此，迫切需要寻找廉价的废水净化材料。为了满足对清洁水的预期需求，本研究旨在利用具有成本效益和环境友好的方法，将牛等动物的骨废料转化为用于水净化的新型复合材料。收集了沙特阿拉伯纳季兰地区屠宰牛的骨废料，并采用热法用于合成羟基磷灰石。利用合成的羟基磷灰石（Ca(PO)(OH)）制备了锰铁氧体/羟基磷灰石复合材料。通过多种复杂程序对该纳米复合材料进行了分类，例如XRD、FE-SEM、EDX、TEM、UV、PL和FT-IR。这种复合材料对亚甲基蓝染料具有出色的光催化活性，亚甲基蓝是工业废物中的常见污染物。此外，合成的复合材料对导致急性水传播感染的 和 细菌表现出优异的抑菌作用。本研究结果表明，与原始羟基磷灰石相比，将锰铁氧体掺入羟基磷灰石中可显著增强抗菌和光催化作用。
